Hot start problems with volvo 460

Oct 24th, 2005, 23:44

I have volvo 460 1980 1721 cm3 B18FP engine.Lastly I have start engine problems.
When the engine is cold in the morning everything is ok, but when i switch the engine off and after a few minutes I want to restart it, the engine speed fluctuates at 400-800 rpm for 3 seconds and then stabilises. Sometimes after a few hours I neede to press the acceleration pedal to max in order to start the engine.
But next day in the morning when the engine is rreally cold the car starts immediately.

Moreover I found some diagnostic codes:
2.3.2
3.1.3
4.1.2

Please if anyone has the same or knows what it is I would be very grateful.

Thanks

this is what iv`e found out but im not sure if it`s the rigth thing iv`e come up with... so don`t relay on this information to be serious ...

diagnostics code:

2–3–2: Adaptive Lambda closed loop control system lean or rich at idling speed.

3-1-3 Tested the charcoal absorption canister valve, Signal faulty

4-1-2 sorry can`t help with this one ...

HI,
I had this problem with a 440 1.8
It turned out to be the brush in the distributor cap that was worn beyond limits, thus the spark was having to jump to the rotor arm, and this was causing the problems starting when the engine was warm, but it ran fine when it was cold!
Hope this helps.
